I'm actually trying to make lists of the best programming music now. First, I'm collecting databases of all the music I can find. The electronic genres are the most elusive... I have a database listing about 16MM tracks and mixes now. Once I get all that I'll finish making those lists.

I have found some decent web stations, but for the most part I just rip hundreds of tracks from dozens of stations at a time and pluck out the couple good songs and then repeat.

I'll get back to you on that.
